Cookie script not working

i have cookie code which is not working dont know whats the problem.This code is working in another script but not in it.

CODE:

function get_cookie(Name) {
    var search = Name + "=";
    if (document.cookie.length > 0) {
        offset = document.cookie.indexOf(search)

        // cookie exist, update expiry date of the same cookie
        if (offset != -1) {
            cookie_info = document.cookie.split('=');
            cookie_info = cookie_info[0]+"=" + cookie_info[1];

            // add 30 days expiry
            var date = new Date();
            date.setTime(date.getTime()+(30*24*60*60*1000));
            var expires = "; expires="+date.toGMTString();

            cookie_info += expires + ";path=/";

            document.cookie = cookie_info;
       }
   }}

function loadCokie() {
    if (get_cookie('popup')=='') {
        alert("hello");

Just a suggestion, but you could just do:

if ( ! localStorage.getItem('visited')) {
    localStorage.setItem('visited', true);
    alert('Hello, new visitor !');
}

and if you have to support older browsers, you'd add the polyfill from MDN that falls back to cookies automagically.

EDIT:

As for your original code, you never execute any of the functions, and if a cookie doesn't exist, it wont return an empty string, so the logic is flawed, I changed it a little :

function get_cookie(c_name) {
  var c_value = document.cookie;
  var c_start = c_value.indexOf(" " + c_name + "=");
  if (c_start == -1) {
    c_start = c_value.indexOf(c_name + "=");
  }
  if (c_start == -1) {
    c_value = null;
  }else{
    c_start = c_value.indexOf("=", c_start) + 1;
    var c_end = c_value.indexOf(";", c_start);
    if (c_end == -1) {
      c_end = c_value.length;
    }
    c_value = unescape(c_value.substring(c_start,c_end));
  }
  return c_value;
}

function set_cookie(c_name,value,exdays) {
  var exdate=new Date();
  exdate.setDate(exdate.getDate() + exdays);
  var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
  document.cookie=c_name + "=" + c_value;
}

function loadCokie() {
  if ( ! get_cookie('popup')) {
    alert("hello");
    set_cookie('popup', 'yes', 30);
  }
}

loadCokie();
